What Happens If You Don’t Rinse Out a Brazilian Blowout?

Brazilian blowouts have become very popular over the last several years. It’s an easy way to add a protective layer to your hair by using a keratin formula while smoothing your hair. But what happens if you don’t rinse out a Brazilian blowout? We’ll show you just that below.

What Is a Brazilian Blowout?

You spent a lot of time and probably money on your Brazilian blowout, but you skipped a few last steps and didn’t rinse it out. Even though the manufacturer recommends you rinse out the treatment, does it really matter?

Most people get a Brazilian blowout to add additional protection to their hair. In addition to the added protection, Brazilian blowouts offer the benefits of smoothing and strengthening strands of your hair.

Those with frizzy, damaged, or overly processed hair take advantage of the Brazilian blowout to improve the health of their hair and a feeling of a new full body and shine.

The overall process of a Brazilian blowout takes about 90 minutes and typically consists of washing your hair a few times, but if you skip the final rinse step, will you mess up the entire process? Keep reading to find out if skipping the rinse on your Brazilian blowout will cause you issues.

The Brazilian Blowout Process

The typical steps with a Brazilian blowout are as follows:

  1. Wash the hair
  2. Apply the Brazilian blowout treatment
  3. Work and leave the treatment in the hair for a specified amount of time to work its magic
  4. Blow dry the hair
  5. Seal the treatment using a flat iron
  6. Final rinsing of the hair

Once you blow dry and seal the hair with the treatment in place, the treatment is virtually done. Rinsing the hair won’t change how the treatment works or what it does to the hair. Rinsing the hair as the final step essentially controls the effectiveness of the treatment.

Keep in mind that it can take up to 21 days for the Brazilian blowout to be fully absorbed by the hair, so if you don’t rinse your hair, any Brazilian blowout treatment left in the hair will be reabsorbed during that time frame.

However, some Brazilian blowout treatments can be tricky and potentially contain ingredients that can negatively impact your hair if not properly rinsed from your hair.

It is recommended that you always rinse your hair afterward to prevent the negative impacts, mess up any results, or any sort of scalp damage.

When Can I Wash My Hair After My Brazilian Blowout?

If you were in a hurry and had to skip the final rinse at the salon, don’t worry! As we already discussed, it won’t negatively impact your Brazilian blowout. However, some people may be curious about when they can wash their hair after the blowout.

Keep in mind that Brazilian blowouts are different from keratin treatments. There are strict rules about what you can and can’t do after a keratin treatment, and the specific amount of days you must wait to wash your hair.

The beauty of a Brazilian blowout is you don’t have to follow any of those rules! You can do whatever you want right after your blowout, and you can get your hair wet anytime after the Brazilian blowout.

After a Brazilian blowout, you want to be gentle with your hair, preferably using a sulfate-free shampoo when cleaning your hair. Using a sulfate-free shampoo can not only extend the life of your Brazilian blowout but also protect your hair from more damage.

Do’s and Don’ts of Brazilian Blowouts

Since we all know how expensive and time-consuming Brazilian blowouts can be, we want to keep them as protected and long-lasting as possible. Let’s discuss a few do’s and don’t you can use for your blowout.


  • Follow the Brazilian blowout treatment instructions.
  • Try to get your Brazilian blowout professionally done.
  • Sleep with extra protection such as a silk pillowcase and preferably a head scarf.
  • Use dry shampoo between washes to help absorb extra oils
  • Limit the amount of heat applied to your hair post-treatment from hair dryers, straighteners, curling irons, etc.


  • Wash your hair too much if you want the treatment to be long-lasting
  • Use shampoos that are made with sulfates. Always choose sulfate-free shampoos and conditioners.
  • Add extra hair creams, serums, or oils to counteract or weight down the Brazilian blowout.
  • Swim without protecting your hair from the chemicals in the water, such as chlorine.
  • Color your hair too soon after your Brazilian blowout.

Here are some other questions people ask about Brazilian blowouts. 

What can you not do after a Brazilian blowout?

There is no downtime with a Brazilian blowout like you would experience with a Keratin treatment. Immediately after a Brazilian blowout, you can resume normal activities such as exercise, swimming, and pulling your hair back with a clip or ponytail holder.

Can I do a Brazilian blowout every month?

Your Brazilian blowout should last approximately 3-4 months, so there is no need to do a treatment every month. Treating your hair too often can cause significant hair health damage.

How long do Brazilian blowouts take?

A Brazilian blowout is a rather lengthy process. One of the most extended steps is allowing the treatment to sit on your hair for about 45 minutes; the entire process is around 90 minutes.

Is a Brazilian blowout the same as a Keratin treatment?

No, a Brazilian blowout does not contain keratin and is not the same as a Keratin treatment. The Brazilian blowout uses amino acids and puts a protective layer on the hair to reduce bulk, volume, and curl.

What type of hair is a Brazilian blowout good for?

A Brazilian blowout is suitable for all types of hair as it helps to improve overall hair health as well as helps to lock in color-treated hair.

So, What Happens If You Don’t Rinse Out a Brazilian Blowout?

Of course, if you’re investing a lot of time and money on a Brazilian blowout in the salon, you might as well let the stylist complete the treatment as recommended by the manufacturer.
